Back in March, perennial indie rock favorites Radiohead filmed a live performance for PBS' Austin City Limits. While the special won't air until the fall, you can now a preview clip featuring a full performance of "Lotus Flower" below.

It's been a big couple of weeks for Pantera fans. First the band premiered a new music video for a previously unheard track called "Piss" at the 4th annual Revolver Golden Gods , and now a previously unheard Dimebag track has been appeared online — apparently to promote a new Dimebag-themed skateboard from Elephant Brand Skateboards. You can stream "Twisted" below.
